where is the day time running light module located on a 1997 silverado

my 1997 silverado day time running lights quite working can any one help me on this??

Check your relay for the DRL. If the light in your dash for the DRL is on(the indicator) is on and your lights are not, you've probably got a bad relay. I'm not sure the exact location, it may be in the under hood fuse box.
